CHAPTER XXIX
SEMI-COMPLEX SENTENCE
§ 1. In accord with the principles laid down in the introductory de-
scription of composite sentences (Ch. XXVI), the semi-composite 
sentence is to be defined as a sentence with more than one predica-
tive lines which are expressed in fusion. For the most part, one of 
these lines can be identified as the leading or dominant, the others 
making the semi-predicative expansion of the sentence. The ex-
panding semi-predicative line in the minimal semi-composite sen-
tence is either wholly fused with the dominant (complete) predica-
tive line of the construction, or partially fused with it, being weak-
ened as a result of the fusing derivational transformation. 
The semi-composite sentence displays an intermediary syntactic 
character between the composite sentence and the simple sentence. 
Its immediate syntagmatic structure ("surface" structure) is analo-
gous to that of an expanded simple sentence, since it possesses 
only one completely expressed predicative unit. Its derivational 
structure ("deep" structure), on the other hand, is analogous to that 
of a composite sentence, because it is derived from two or more 
completely predicative units — its base sentences. 
There are two different causes of the existence of the semi-
composite sentence in language, each of them being essentially 
important in itself. 
The first cause is the tendency of speech to be economical. As a re-
sult of this tendency, reductional processes are developed which 
bring about semi-blending of sentences. The second cause is that, 
apart from being economical, the semi-composite sentence fulfils 
its own purely semantic function, different from the function of the 
composite sentence proper (and so supplementing it). Namely, it is 
used to show that the events described in the corresponding sen-
tence parts are more closely connected than the events described in
